Description

Technical Field

[0001] The utility model relates to a support-free magnetic pump for a fish tank. Background Art

[0002] The existing bracket-free magnetic pump for fish tanks can refer to the US patent application number: US20060210412A1. The patent consists of two parts: a pump head and a motor. A first magnetic coupler and a second magnetic coupler are respectively installed between the pump head and the motor. The rotational torque of the motor rotor is transmitted to the rotational torque of the impeller in the pump head by using the magnetic coupling of the first magnetic coupler and the second magnetic coupler. In this structure, the pump head and the motor use the principle of mutual adsorption of the first magnetic coupler and the second magnetic coupler, so that the pump head and the motor are respectively adsorbed on both sides of the glass wall of the fish tank, so there is no need to install a bracket.

[0003] However, this structure has the following problems: 1) Since the glass wall of the fish tank is smooth, the pump head and the motor are adsorbed on the glass wall of the fish tank solely by the principle of mutual adsorption of the first magnetic coupler and the second magnetic coupler. Due to the total amount of the pump head and the motor themselves, it is easy for the pump head and the motor to slide on the glass wall of the fish tank, causing the pump head and the motor to be misaligned, resulting in the first magnetic coupler and the second magnetic coupler being misaligned, affecting the transmission. Summary of the invention

[0004] The utility model provides a support-free magnetic pump for a fish tank, which is used to solve the technical problem that in the prior art, a pump head and a motor are adsorbed on the glass wall of the fish tank solely by the principle of mutual adsorption of a first magnetic coupler and a second magnetic coupler, and that due to the total amount of the pump head and the motor themselves, the pump head and the motor are easily caused to slide on the glass wall of the fish tank, causing the pump head and the motor to be misaligned, resulting in the first magnetic coupler and the second magnetic coupler being misaligned, thereby affecting the transmission.

[0005] The technical solution of the utility model is achieved in this way:

[0006] A support-free magnetic pump for a fish tank, comprising a pump head and a motor, wherein:

[0008] The motor comprises a housing, a stator assembly, a rotor assembly, a rotating shaft and a second magnetic coupler. The stator assembly, the rotor assembly and the rotating shaft are installed in the housing, and one end of the rotating shaft is connected to the second magnetic coupler.

A second closed cavity is arranged below the top surface of the housing, and the second magnetic coupler is installed in the second closed cavity.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] 1. When the utility model is installed, the first vacuum suction cup on the bottom surface of the pump housing of the pump head is adsorbed on the inner side of the glass wall of the fish tank, and the second vacuum suction cup on the top surface of the motor housing is adsorbed on the outer side of the glass wall of the fish tank, and a magnetic attraction effect is formed between the first magnetic coupler and the second magnetic coupler, which are respectively leaned against the glass wall of the fish tank, thereby forming a more stable installation.
